All of them were imported from other countries, with a majority from Africa (93.8%, 121/129) and a minority from other Asian nations (6.2%, 8/129). Blood test was conducted in the City for 116 034 febrile patients, with a positive detection rate of 0.1%. The disease onset showed no significant seasonal and regional variations. The reported cases comprised 127 male cases, concentrated in the 39-49 age group. They were mainly workers, peasants, and unemployed persons.
